To all whom 'it may concern.'

lle it known that I,Joeerii C; Rmx acitizen of the United Stutenresiding at Lrie, in

the county of Erie iiii ..Stnte of Penne lvnnizi, have invented certainnew and use nl 'l|n| n'o\e|iieiits in File-Sliarpeners und Ido herebydechire-the following to lie a full, elem', und exact descri tion of theinvention, .Laut-h is will enable otiers skilled in the url'. lo whichit appertnins to ineke und use the suine, re ference being lntd to theaccompanying drawings, sind to the letters of reference nnirlcedthereon, forming part of this specilieul'ion. i

My invention relntes to file-Sharpeners, und hns for its object theconstruction of u. mechanism operating to project iin abrasiveinnterinl, such es granulated vcnrborundum mixed with fluid, by menneofsteam apiiinst the face of n file nt Such an angle tiat it operates tosharpen the teeth of a Iile.

l'lie Vtentures of my invention are hereinafter set forth und explained,und illustrated in the necoinpanyiiig drawin s, in which:

Figure 1 is a central longitudinal section of on ul'ipurntns embodying.Emy invention. Fig. 2 is n front end view thereof. Fig. 2l showsaneiilnrged detail Vview of one feature of my apparatus. Y.

ln these drawings illustratinu iny inven tion, A. is :in inclosed eusewliic ,is smaller nt its front end thonet its reu-r end, mounted on nfreine A with its front ehd considerulily lower than its rear end, andis )rovided with baille plotes B, B und B, an a steam outlet. C nt thotop of the rear end thereof.` 'the upper 'half a of the woll closing thefront end-of' the case A is provided with an opening u.' and. under thebase otsaid oponing o there is an extension A ofthe ense A, und intliisextenuion A* there is n. siplion or steinn injector T), the nonzleor 4jet opening (l nl which extends i-nwiii'd under the opening; u., thesteinn su ply (pipe E extending cutwnrd through t e en of tliepnrt A" ofthe rose A, where it is provided with n sluit-olf vulve r: andextendingr llieielfioni is n snitulile Hltoani Iwnppllv pipe lli', undthe suction pipe D of snif injector extends downn'nrd I`1oui theinjector l) suhfilunl'iully lo tlnl hot.- loin of tho ense A. l

In the `lower pui-t of the l'i'ont ond oFllie 98Se-A, l mount nroolvsliufi. F' one Mdo-l"- which iS mounted in n beuiing fin tho unseA, and the other exil-nds lhroue'h the end ol ibo projection A Onlineoise A, willie il n ltherewith flowing through provided with an oeratingernnk F', and on this rockshaft l4 there are downwardlyprojecting fingers F which extend downwnrd nearly to the bottom of thefront portion of the case A, so that by operating the roek-slinft F thealii-odin materiel in the bottom of the front ond ol the case A where itaccumulates b reason of the-inclination thereof, can be :eptvstirred upin suitable condition to be eiii'ried upward by the injector suctionpipe D Throuoh the end A of the case A' there is un overl ow pipe Hwhich determines the height o "t e water level in the ease A, thesurplus witter and abradinfmiiterial mixed e pipe H into a settling tankHf mounted in the use of thev frame A. This tank is nlsoprovided with unoverflow pipe li and a pipe h for drowing oil' the water when itisdesired to remove the accumulated ebradng materiely from said tank H.Foisupplying fres'habrading m-iiteriall .to said apparatus, I insert an.

upright pipe I in the case A, substantially directly above and sli htlinfront of the dischar re nozzle nl of t e injector D so that materiafalling from said pipe I will fall in the line of the Steam jet issuingfrom the nozzle d. This pipo is provided with sliding valves I having anoperating handle J by ineens whereofthe valves I con be operated so :isto close one und 'open the other, whereby a fixed amount of'abradingmaterial ciiiibe discliai'wed at each movement of the vulves I. Anil onthe top of the pipe I there is a hopper K to retain a supply of abradingmateriel.

llroni the ntenin supply pipe E a pipe L extends npwnrd aiidis providedwith n shut.` oll viilve L. ltendin there is a pipe M whic partiullyacross the upper purt where it is provided with steam j et openings m m.pointing towurcl eeeli other on ncross extends into und 'the upper portof the openingba in the ense .Meo t nit n tile after being s mitted tothe :ielon of the nlirznling ninterial issuing from the nozzle d can berinsed up i-n line with the Hteinn jets m und me and'be cleaned.

lliiving thus described my invention so as to enable others to constructand utilize the sinne, what. i claim os new und desire to secure byLetters-Putent is: h

l. the combination in a tile :sharpening ppnroius, of :in .inclined ouenlowing n n openingl in the upper pin-t ol its lower enel,

from the valve L4 sie of the cose A l ibo llt

and a steam disschurge openin near its u per end, a series of rigid deactors in t e upper part of said case, an extension on the lower end ofsaid case below the opening therein, an injector within said extension,a suction pipe leading from said injector substantially to the bottom ofthe lowermost part of the extension on said case, and steamjet pipesoperatinfr toward each other across the upper part op the opening in thelower end of so id case, substantially as set forth.

2. The combination in a, file sharpening uppamtns of an inclined casing,rigid dellertors in the upper part of said casing, an injector in thelower part of Said casing operating toward the first of said deflectors,a suction pipe lendin from said injector to the lower part of sai eosinf, a ipe in the ngper part of said casing or isehargin;r n mdingmaterial into said cose in front o the in jeotor nozzle, and vulvernecluininn'i in .said pipe to control the discharge of abrmlingMaterial therefroni, substantially as set ort In testimony whereof Iaffix my signature, 23
